1. NRC Question

The FHA radiological consequence analysis for Amendment No. 236 uses X/Q valuesthat were derived assuming a diffuse source release from the reactor building; i.e., theactivity being released is assumed to be homogeneously distributed throughout thereactor building and leak over the entire reactor building surface. In reality, the releasesare likely to occur through the unit vent or through an open personnel, equipment, and/oremergency hatch. Please confirm that the diffuse source control room X/Q values usedin the Amendment No. 236 dose assessment bound the atmospheric dispersioncharacteristics for releases from the unit vent, personnel hatch, equipment hatch, andemergency air lock.

Response

As stated above, the dose previously calculated for the Fuel Handling Accident InsideContainment (FHAIC) radiological consequence analysis for Amendment No. 236 used aX/Q value that was derived assuming a diffuse source release from the reactor building;i.e., the activity being released is assumed to be homogeneously distributed throughoutthe reactor building and leak over the plane of the reactor building surface perpendicularto the control room air intake tunnel. This previously calculated diffuse X/Q value was3.40E-04 sec/m 3for a 0-2 hour release.

In order to confirm that the X/Q value selected is the bounding value, it was decided thata X/Q for the equipment hatch, unit vent, personnel air lock, and emergency air lock(positioned within the equipment hatch) would be re-calculated for the control roomintake using ARCON96 and the guidance provided in Regulatory Guide 1.194. Pleaserefer to the enclosed calculation (Enclosure 2) for additional details. Enclosure 3provides an electronic disk containing the ARCON96 files as well as the same four yearsof meteorological data (1992, 1993, 1995,1996) used to develop the existing licensingbasis X/Q values previously reviewed and approved in TMI-1 Amendment Nos. 210 and215, dated April 15, 1999 and August 24,1999, respectively. This meteorological datawas used in the calculation provided in Enclosure 2 to develop the revised X/Q valuesdescribed above. As discussed in Enclosure 2, upper level wind data is not used in thenew X/Q determinations. The associated upper level wind speed instrument is notrequired by TMI Unit 1 Technical Specifications nor is it necessary for this analysis sinceonly ground level release X/Q values are being determined. Consistent with the previouslicense amendment request supporting TMI-1 Amendment No. 210, referenced above,since less than 90% of the 1994 TMI meteorological data was recovered, this year isexcluded.

These new X/Q values are summarized below:

Location 0-2 Hours X/Q (sec/m 3)Unit Vent: 5.34E-04Personnel Air Lock: 2.68E-04Equipment Hatch: 4.51 E-04Emergency Air Lock: 4.47E-04

Since releases can occur through the unit vent or through open personnel, equipment,and/or emergency hatch, the highest X/Q (5.34E-04 sec/M 3 corresponding to the unitvent) is used to develop the revised control room dose consequence for the FHAIC.


Note that the filter that is available and aligned on this pathway is still not being creditedin the dose analysis.

Regarding the calculated dose to control room operators, the X/Q value is a directmultiplier in the dose equation. Therefore, since the fuel handling accident occurs over atwo-hour period, the X/Q ratio (new / previous) for the 0 to 2-hour release period can beapplied as a direct multiplier to the originally calculated control room dose as follows toobtain the new maximum calculated dose:

0.655 Rem TEDE x (5.34E-04 / 3.40E-04) = 1.028 Rem TEDE

Where:

0.655 Rem TEDE = originally calculated/submitted/approved dose5.34E-04 = highest new calculated X/Q value (sec/m 3) the unit vent3.40E-04 = previously calculated diffuse source X/Q value (sec/M 3)

The revised FHAIC calculated control room operator dose of 1.028 Rem TEDE, based onusing the bounding X/Q value described above, remains well below the regulatorycriteria of 5 Rem TEDE specified in 10 CFR 50.67 and GDC-19. The previouslyanalyzed Exclusion Area Boundary and Low Population Zone dose consequences arenot impacted by this change.

Note that this control room dose value will be further revised as a result of changes beingmade to the dose analysis model assumptions and parameters in response to additionalNRC review questions. These changes have no impact on the above boundingcalculation for the X/Q value. The final calculated dose consequences for the FHAIC arebeing submitted separately and are expected to remain well below the regulatory criteria.

2. NRC Question

The FHA radiological consequence analysis for Amendment No. 236 uses X/Q valuesthat were derived assuming all infiltration into the control room (both filtered andunfiltered) occurs through the control room yard air intake. Using the results of the tracergas testing performed on the TMI-1 control room envelope, please confirm that there areno potential unfiltered inleakage pathways during the control room isolation mode thatcould result in X/Q values that are higher than the control room yard air intake X/Qvalues.

Response

The tracer gas testing report confirms that there are no specifically identified potentialunfiltered inleakage pathways in the control room isolation mode that could result in X/Qvalues that are higher than that for the control room yard air intake. This is furtherdemonstrated by the fact that differential pressure readings between all areas within thecontrol room (CR) envelope and outside areas were shown to be positive. Positivepressure in the CR with respect to outside areas precludes inleakage through theboundary walls. This implies that the more credible source of inleakage would bethrough the air intake tunnel as currently described. The maximum inleakage asmeasured by the tracer gas test was during operation of the "A" train at 233 +/- 129 cfm


(189 +/- 103 cfm for the "B" train). Additionally, the maximum assumed unfilteredinleakage value used in the TMI-1 design basis calculations is 1,000 cfm, which providessignificant margin compared to the maximum measured values. The personnel air lock,although located within the Intermediate Building, is in a location close to the ControlBuilding. It is unlikely that leakage through the personnel air lock would be directedtowards the Control Building that could contribute to unfiltered inleakage through the CRboundary walls. This is partially due to the positive pressure in the Control Building aswell as the fact that leakage from the air lock would be into the Intermediate Buildingand/or Turbine Building. The Intermediate Building normal exhaust pathway is throughthe unit vent. The Turbine Building exhaust pathway would be farther away and morefavorable. For conservatism, the X/Q for the personnel air lock was based on its locationwithout credit for any release-containing structures. The more credible inleakage pathinto the CR is through the air intake tunnel. Therefore, use of the highest calculated X/Qvalue (unit vent, personnel air lock, equipment hatch, or emergency air lock), asdescribed in response to Question No. 1 above, ensures that the maximum crediblecalculated dose is determined. Based on the above, it is concluded that other potentialpathways do not represent credible unfiltered inleakage pathways to the CR during CRisolation mode of operation.

1.0 PURPOSE

This calculation, C-1 101-826-E410-030, Rev. 0, presents new atmospheric relative concentration (X/Q)values for Alternative Source Term (AST) accident evaluations for the Three Mile Island Station asadditions and changes to those provided in Reference 9. The purpose of this calculation is to determine theYard Intake relative concentration values (X/Q, in sec/M3) resulting from certain postulated accidentalradiological release locations that may be different from those in Reference 9. The values resulting fromthis calculation can be used as input for the determination of radiological doses using the AlternativeSource Terms (AST) per Regulatory Guide (RG) 1.183 (Reference 1) for these new release locations.

The X/Q values resulting at the Yard Intake are calculated using the NRC-sponsored computer codeARCON96 (Reference 2) consistent with the guidance in RG 1.194 (Reference 3). This analysis ispresented in Section 2.0 below.

2.0 ARCON96 ANALYSIS OF YARD INTAKE X/Q FOR NEW RELEASE LOCATIONS

2.1 Identification of Computer Programs/Method of Analysis

ARCON96 is a commercial software package designated by Washington Group International as NU-830,an "active" program applicable to nuclear safety related analyses as well as non-safety related studies andevaluations. Its use is principally control room habitability assessments. The NU-830 code has beenverified for 0-2 hour, 2-8 hour, and 8-24 hour centerline and sector X/Q averages and the 95% maximumX/Q. This verification is in accordance with Revision 4 of the Washington Group International NuclearEngineering Standard for Computer Software Control, NEP-09. Revision 0 of NU-830 was verified forground-level and zero exit velocity uncapped vents, and Revision 1 was verified for zero exit velocity stackreleases.

ARCON96 Program Description [excerpted from NUREG/CR-6331 Rev. 1 (Reference 2)]

ARCON96 is a straight line Gaussian dispersion model used in control room habitability assessments forestimating dispersion in the vicinity of buildings to calculate relative concentrations at control room airintakes that would be exceeded no more than five percent of the time. The basic diffusion modelimplemented in the ARCON96 code is a straight-line Gaussian model that assumes the release rate isconstant for the entire period of release. This assumption is made to permit evaluation of potential effectsof accidental releases without having to specify a complete release sequence. Ambient atmosphericconditions measured in accordance with RG 1.23 (Reference 4) are input to ARCON96 by way of asequential hour-by-hour meteorological database of jointly measured wind speed, wind direction, andPasquill stability class, as derived from the vertical temperature difference recorded at representativeelevations (i.e., tower levels).

ARCON96 permits evaluation of ground-level, vent, and elevated releases. Building wake effectsare considered in the evaluation of relative concentrations from ground-level and vent releases as afunction of the ratio between the effluent vertical velocity and the release-height wind speed, usingthe same procedure used in the NRC XOQDOQ code (Reference 5).

Diffusion coefficients used in ARCON96 have three components. The first component is the diffusioncoefficient used in other NRC models, for example XOQDOQ, and PAVAN. The other two components

CALCULATIONNO. C-1101-826-E410-030 I REV. NO.0 | PAGE 5 of 9

are corrections to account for enhanced dispersion under low wind speed conditions and in building wakes.Derivations of the low wind speed and building wake corrections are described by Ramsdell and Fosmire(Reference 6). Parameter values for the correction factors are based on analysis of diffusion data collectedin various building wake diffusion experiments (Reference 6). The experiments were conducted under awide range of meteorological conditions. However, a large number of experiments were conducted duringlow wind speeds, when wake effects are minimal. The wake correction model included in ARCON96treats diffusion under these conditions much better than previous models. Thus, the diffusion coefficientsin ARCON96 account for both low-wind speed meander and wake effects.

ARCON96 calculates relative concentrations using hourly meteorological data. It then combines thehourly averages to estimate concentrations for periods ranging in duration from 2 hours to 30 days. Winddirection is considered as the averages are formed. As a result, the averages account for persistence in bothdiffusion conditions and wind direction. Cumulative frequency distributions are prepared from the averagerelative concentrations. Relative concentrations that are exceeded no more than five percent of the time(95th percentile relative concentrations) are determined from the cumulative frequency distributions foreach averaging period. Finally, the relative concentrations for five standard averaging periods used incontrol room habitability assessments are calculated from the 95th percentile relative concentrations.

2.2 Assumptions

The following dimensions were assumed based on minimizing distances from the release to the intake andverified as conservative during a site walkdown on May 24, 2005:

* Unit Vent release height 6 ft above the top of the Reactor Building.* Personnel Hatch release at the top of a 6 ft doorway positioned on the platform shown in

Attachment A.

In addition, the Equipment Hatch and Emergency Airlock release heights were set equal to the intakeheight.

2.3 Inputs

2.3.1 Meteorological Data

The Three Mile Island meteorological tower data for the four years 1992, 1993, 1995 and 1996, as suppliedby Exelon (Reference 7), were applied in the ARCON96 modeling analyses. Wind measurements weretaken at tower elevations 100 ft and 150 ft.

Executing ARCON96 requires the meteorological input file to contain two (2) wind levels (lower andupper), however, since the tower data are validated at the 100 ft level only, the 100 ft wind data weresubstituted for the 150 ft wind data, resulting in an ARCON96 meteorological database with two identicallevels of wind data to represent the lower and upper level required input.

Attachment B includes the four yearly wind rose diagrams based on the 100 ft meteorological tower winddata and Attachment C contains the joint wind direction, wind speed, and stability class distribution tablesfor the same data.

2.3.2 Yard Intake Scenarios

The release points identified for consideration at Three Mile Island are the Unit Vent, Personnel Hatch,Equipment Hatch, and Emergency Airlock. The locations of these release points are shown in AttachmentA (Reference 8).

All release points were modeled in ARCON96 as ground-level releases. Aerodynamic building plumedownwash effects are present for ground-level releases; therefore, in accordance with RG 1.194, thebuilding area perpendicular to the wind direction is utilized. For all scenarios, the Containment Buildingarea of 2127 m2 was utilized (Reference 9).

The center of the Yard Intake is located 18 ft (5.49 m) above grade as seen in Attachment D (Reference10), and is identified with respect to the release points in Attachment E (Reference 11).

ARCON96 requires a horizontal source-receptor distance to be input, which is defined in RG 1.194 Section3.4 as "the shortest horizontal distance between the release point and the intake". However, for releases inbuilding complexes, a "taut string length" can be utilized as justifiable. For the Personnel Hatch this "tautstring length" (calculation shown in Attachment F) was utilized to account for the intervening FuelHandling Building. Per a Washington Group International phone conversation with Mr. Steve Lavie ofNRC on May 17, 2004, when the "taut string length" is utilized, the intake and release height should be setequal to each other so as not to also take undue advantage of the slant distance that ARCON96 calculates.Therefore, for the personnel hatch, the intake height was set equal to the release height, of 3.5 m.

The releases for the Yard Intake modeling scenarios are each treated as a point source, and areconservatively assumed to have a zero (0) vertical velocity, exhaust flow and stack radius. TheARCON96 input parameter values were set in accordance with RG 1.194, Table A-2 (e.g. surfaceroughness length = 0.2 m; wind direction window = 90 degrees, 45 degree on either side of line of sightfrom source to receptor; minimum wind speed = 0.5 m/s; and averaging sector width constant = 4.3).

A summary of ARCON96 input parameters and certain output meteorological data statistics is shownbelow in Table 2-1.
